This is a sequence diagram that shows the representation of selection and loop.

frame: box around part of diagram to indicate if or loop

• if -> (opt) [condition]
• if/else -> (alt) [condition], separated by horizontal dashed line
• loop -> (loop) [condition or items to loop over]

In this example:

For each of the line item in the order - if the item value > 10,000 then dispatch through careful Distributor, else dispatch through regular distributor.

If any items fall into “needsConfirmation” condition the confirm message will be sent to the messenger.
